Girling shocks were all the same length with different springs(but only 2 from memory) accross all the fours
If CL 450 are right length i might try those, a lot of CB 450 parts were used on 500 four and thats not much different, then again thats two suppositions in a row and they always say if you assume you make an ass out of you and me!
Well they do need to pivot as swing arm moves just not much
